Conventional and small modular reactors
Vintr, Lukáš ; Lisá, Hana (referee) ; Milčák, Pavel (advisor)
This thesis deals with nuclear energy. It contains a brief history of the development of this industry and provides insight into the process and control of the fission chain reaction used in nuclear reactors. It also describes conventional reactor types and the current state of their use in the world. It then mentions the research objectives set by the Generation IV International forum. Finally, it defines small modular reactors, describes a number of conceptual designs, and presents an analysis of the current state of their development, together with the possibilities of their use for the production of electricity or process heat.

Possibilities of using small modular reactors in the heating industry
Duchoň, Jan ; Šnajdárek, Ladislav (referee) ; Milčák, Pavel (advisor)
This bachelor thesis deals with nuclear energy, mainly focusing on small modular reactors and their possible use in heating industry. The first chapters are focused on history of nuclear energy, explaining key concepts and describing nuclear reactors and their principle in general. One of the crucial topics, covered in the following section are small modular reactors, key examples of SMRs, their wide range of uses and comparison of advantages and disadvantages of this type of reactors. Next chapter consists of introduction to heating industry, description of situation in Czech republic and analysis of Czech heating plants. The final chapter uses acquired information to assess potential use of SMRs in Czech heating industry as a replacement for fossil fuel heating plants.

Circuits of nuclear power plants
Pavlíček, Martin ; Kudela, Libor (referee) ; Milčák, Pavel (advisor)
This bachelor's thesis deals with the history and beginnings of nuclear energy, an explanation of the basic knowledge of nuclear energy and an introduction to the issue. Then, the division of nuclear reactors according to various criteria is described. Furthermore, the solution of individual circuits in a nuclear power plant is described according to the type of reactor used. The individual circuits are described at the Temelin nuclear power plant. The last part deals with nuclear safety and various safety systems, without which a nuclear power plant could not be started.

Nuclear Fuel and its Behavior during Burn-up
Matocha, Vítězslav ; Foral, Štěpán (referee) ; Katovský, Karel (advisor)
The point of this bachelor’s thesis is to characterize different types of nuclear fuels and their behaviour during the process of burning-up. Futher, basic types of nuclear reactors are mentioned, as well as their history and different kinds of nuclear fuels used in these reactors. Then there are pieces of information about fuel cycles and fuel burning-up. Furthermore, the thesis concentrates on the changes, which happen in the nuclear fuel during the process of burning-up, such as swelling and cracking. In its other parts, this bachelor’s thesis deals with fission products, mainly gas fission products are mentioned here. At the end of this thesis, a simple model of nuclear fuel burning-up is created. This model follows concentration of izotopes of uranium and plutonium during fuel burning-up.

Analysis of possibilities for use of III. and IV. generation of nuclear reactors for the Czech Republic
Gajdzica, Lukáš ; Kopřiva, Radek (referee) ; Kopřiva, Radek (referee) ; Matal, Oldřich (advisor)
The thesis deals with the analysis of possibilities for use of III. and IV. generation of nuclear reactors for the Czech Republic. Introduction deals with basic principles of nuclear energetics and fuel cycle which is closely associated with the issue and its development and application in practice will have a significant effect both for choice of future types of nuclear reactors of IV. generation and the matter of settlement with spent nuclear fuel. In other parts the thesis deals with the present state of nuclear energetics in the Czech Republic, compares concrete chosen types of nuclear power plants of III. generation and generally describes nuclear reactors and power plants of IV. generation. Final part of the work is focused on questions concerning the possibility of construction of new blocks of nuclear power plants in the Czech Republic and presents concrete recommendation from author´s point of view.
